Image forming apparatus capable of converting the resolution |
摘要 |
According to the image processing apparatus of the present invention, image data are entered with an input resolution of 16 dots/mm, yet allowing the use of a conventional image processing system with a resolution of 8 dots/mm, and there can be produced an image better in quality than a conventional one. First, pixel data with an input resolution of 16 dots/mm are subjected to resolution conversion using a resolution converting unit 21. The resolution conversion is made by an odd-numbered pixel thinning processing when the apparatus mode is set to a binary mode, and by a two pixel averaging processing when the apparatus mode is set to a half-tone mode. Then, pixel data of which resolution has been converted into 8 dots/mm, are supplied to an image processing unit 22, where an image processing is then executed on the pixel data.
